2 gay guys are walking down the street and they notice this dog licking his crotch. The first gay guy goes "Boy...don't you wish you could do that?" The second gay guy goes "Yeah, but I'm afraid he'd bite me."
Please just remove my comment without banning me if a mod happens to find this one too offensive. For the record I have friends that are gay and I wasn't trying to start a homophobia thread or anything like that with my joke.
